IBM® z/OS Debugger Utilities: z/OS Debugger Setup File
Setup files can save you time when you are debugging a program that needs to be restarted multiple times. Setup files store information needed to allocate the necessary files and run a single job-step with z/OS® Debugger either in MVS batch or TSO foreground. You can create several setup files for each program; each setup file can store information about starting and running your program in different circumstances. To create and manage setup files, select z/OS Debugger Setup File (option 2).
